Intro:One of the most spread misconception about sleep is that sleep is just a matter of our bodies turning off for couple of hours , and then turning back on when we are awake. Many of us also think that sleep is a passive, constant and unchanging process. Yet, what we don’t realize that sleep is in fact a very active state. Our bodies move frequently during the night, but what’s even more striking is that our brain activity is more varied than it is when we are awake.
